Pull the audio track out of a video, or convert an audio file from one format to another. Drop in an MP4, MOV, MKV, WebM, or AVI recording — or a WAV, FLAC, M4A, OGG, or AAC file — then choose the output format, bitrate, and sample rate. Everything is decoded and re-encoded inside your browser tab, so meeting recordings, lectures, and interviews never leave your machine.

Cut a few seconds out of an MP4, MOV, WebM, MKV, or AVI and turn them into a GIF or an animated WebP. Trim on a timeline first, then set the frame rate, width, palette, speed, and loop. GIFs are built with a two-pass palette so they come out clean instead of banded, and the whole thing runs inside your browser tab.

Cut a section out of a video, or drop the dead time at the start and the end, without re-encoding it. The selected span is copied stream for stream, so the picture is bit-for-bit what it was and the copy itself takes seconds. The timeline shows where the source keeps its keyframes — a lossless copy can only begin on one — and a re-encode mode is there for cuts that have to land between them.

Save still images from a video: one for a cover, one every few seconds across a range, or a fixed number spread evenly over it. FFmpeg seeks from each timestamp, decodes at the source resolution, and reports the time of the frame it reached. Stills come out as PNG, JPEG, or WebP, one at a time or all together as a ZIP.

Change the resolution of a video, crop it to the part that matters, or give it a different shape: 9:16 for a vertical feed, 1:1 for a square post, 16:9 for a player. Drag the framing box to choose what a crop keeps, or fit the whole picture inside bars in a flat colour or a blurred copy of the video. FFmpeg re-encodes everything inside your browser tab.

Reduce a video until it fits wherever it has to go: an email attachment, a chat app, an upload form with a fixed cap. Give it the limit in megabytes and the bitrate is worked out from the length of the clip, with resolution, frame rate, and audio as the levers you can spend. It says whether the target is realistic before encoding starts, and whether the finished file cleared it. FFmpeg runs inside your browser tab.

Move a video into a format that plays, imports, or uploads where you need it: MP4, MKV, WebM, MOV, AVI, and seven more. Most conversions only change the wrapper, so the picture and sound are copied across untouched in seconds rather than re-encoded — and the tool says which streams are being copied, which have to be re-encoded, and why, before it starts. FFmpeg runs inside your browser tab.

Read what a video or audio file actually contains: the container, the codecs inside it, bitrate, resolution, frame rate, channels, chapters, and every metadata tag. It also answers the things a field list leaves out, such as where an MP4 keeps its index, how its average and base frame-rate readings compare, and whether this browser can decode the audio. FFmpeg runs inside your browser tab.

Join several clips into one video, in the order you choose. Clips that came off the same camera or recorder are stitched packet by packet without being decoded, so the join is lossless and takes seconds; clips that genuinely differ are brought to one frame, one frame rate and one audio layout, and the tool says which property forced that before it starts. FFmpeg runs inside your browser tab.

Mute a video, swap its soundtrack for a file of your own, lay music under what is already there, or make a quiet recording louder. The picture is never touched: the video track is copied packet for packet in every mode, so it is never re-encoded, HEVC and AV1 are no obstacle, and the only thing that ever has to be rebuilt is the sound. The timeline shows where an added track starts, how far it reaches and what gets cut off, and you can hear the balance before rendering. FFmpeg runs inside your browser tab.

Turn an ordinary flat video into a side-by-side stereo pair you can see in 3D with no glasses at all, just by crossing or relaxing your eyes. A depth model reads every frame to work out what is near and what is far, then a second viewpoint is built from it by shifting pixels in proportion to their depth. Preview a single frame and the depth map behind it before committing to a run, choose parallel or cross-eyed output, and convert a clip of any length — it is processed in segments, so memory depends on frame size rather than duration. The model and FFmpeg both run inside your browser tab.
